The Serial Encoder Command is a 32-bit, channel specific, structure element. It specifies the bit length
(resolution), status bits, data type, conversion method, trigger enable, trigger mode, parity, and command
code of the serial encoder channel.

Bits [31 – 16]
specify the command code. This field is protocol specific.
Bits [15 – 14]
specify the parity. This field is protocol specific.
Bit 13 specifies the trigger mode.
Bit 12 is the trigger enable toggle.
Bit 11 specifies the conversion type. This field is protocol specific.
Bit 10 is the data ready bit, read only.
Bits [9 – 6]
specify the encoder status field. This field is protocol specific.
Bits [5 – 0]
specify the serial encoder bit length (single-turn + multi-turn).
Following, are examples for setting up the control and command words for each of the supported protocols.
